Tadashi organized his organization based on the Cult of the Abandoned City and in a sense became a priest there, but due to his own selfishness he changed it.
Many people came there to pray to the god and make offerings, all of which contributed to Tadashi's selfishness and psychopathic tendencies, especially when two girls were literally able to force him to take drugs one day. He deceived people by saying that he was the messenger of God, and everyone did what he said, but because of his arrogance which increased every day, people began to suspect him and doubt him, which he initially did not understand.
People started calling him a hypocrite and at first there wasn't much noise, but eventually the whole city turned against him and his church.
He was caught and then he was literally chained to a large cross, in other words, it was an execution, even if he begged for his life, but his actions were unforgivable.
Tadashi was hanging over the fire, his hands were tied to the cross with an iron chain and his legs too. Blood poured out of his head, and his palms were also stained with his own blood.
People shouted that he was a hypocrite and that he should go back to where he came from. Everyone hated him, especially the poor people from whom he literally took everything.
Tadashi was surprised at first, but then he looked away from the crowd and smiled slightly.
"This is such a beautiful ending, isn’t it?"
